Specicaton of Letters Patent.

Patented Apr. 26, 1921.

Application filed July 17, 1917. Serial No. 181,157.

To all wlw/m, t may concern Be it known that I, AUGUST H. BAsTiAifr, acitizen of the United States, and a resident of Hillsdale, Multnomahcounty, State of Oregon, have invented a certain new and usefulFImprovement in Baker-Gages lfor Crosscut-Saws, of which the followingis a specification.

The object of this invention is toprovide an instrument for gaging andtacilitating the proper shaping and finishing of the iakei's ofcross-cut saws.4 Also to adapt this instrument to infinite variationsfor said purpose. Also to provide means within the instrument foreilecting its minute adjustment.

These objects, and incidental features, I attain by the deviceillustrated in the accompanying drawings, in which:

Figure l is an elevation of one sideoit my device; y

Fig. 2 is an elevation ot the opposite side; and

Fig. 3 is a bottom or inverted' view of the gage plate of my device.

The frame or body piece, a., may be .ot the usual construction, and isprovided with set or clamping screws b, o for clamping the file inplace, in fiat and edgewise positions.

On the frame or body piece, @,is supported a gage plate c, consisting ofa body having an integral lateral flange c, made with a slot o2 to admitthe ralier, as illustrated in Fig. 2. The top or working face of theslotted. flange of the gage-plate serves both to gage and to iinish theralrers; the iiler iiling right down to the surfaceofthis ange, which iscase hardened.

The support of the gage-plate c consists of two cooperating parts eachpermitting the gage plate relative, arcuate and lineal adjustment; forexample, two set-screws d,

c, extending through slots 7", y of the gageplate and threaded into thebody-piece a; V'he set screw e being located at the approximate centerof the gage plate, and the set screw (Z to one side oit this center andthus at one end of the gage plate. But l do not limit myself to anyspecific construction in this connection.

z' is a micrometer screw, in other words, a screw of very fine thread;such screw being journaled in the body piece a and bearing desired`plane,

n adjustable against thegage plate o to one side of its `tratcd by thedotted outline of a section of a cross-cut saw shown in Fig. 2.

The set screws d and e being' first released, the gage plate may then berotated on the set screw Z by manipulating the micrometer screw z' untilthe top or working i'ace of the flange c of the gage plate o is placedin the and the gage plateis then secured in place or adjusted bytightening said set screws. l

.l claim:

l. ln. a tool of the character body-piece comprising portions spacedapart intermediate web, a gage-plate pivotally mounted on such web andprovided with aslot, a clamping screw for the gage-plate located at oneside of the aXis of rotation of the latter, such clamping screw beingthreaded in the web and bearing insaid slot, and an screw having a finethread engagtwo lateral edge and connected by an described, va

ing in thebody-piece, said' screw bearing against the rim of saidgage-plate, to one side of its aXis of rotation and operable to give thegage-plate very slight adjustment about its pivot.

2. ln a tool of the character described, a body-piece comprising twolateral edge portions spaced apart and connected by an iurtermediateweb, a gage-plate pivotally mounted on such web and provided with aslot, the pivot bearing in a slot of one ot' the parts therebyconnected, whereby they gage-plate is permitted lineal aswell as arcuateadjustment, a clamping screw for the gage-plate located at one side ofthe axis of rotation of the latter, such clamping screw being threadedin the other part and bearing in said slot, and an adjustable screwhaving a fine thread engaging in the body-piece, said screw bearingagainst 'the rim of said gage-plate, to one side of its vairis ofrotation and operable to give the `gage-plate very slight adjustmentabout its pivot.

AUGUST H, BASTIAN.
